Starts off well
Then it sounds like you've gone tone deaf. Sounds like a video game song, and then it sounds like a video game where you're about to die. Make sure you do your song in the same key. Other than it hurting my ears in that way, good job. Could use some build up and stuff like that. I'm going to assume you're using FL Studio, if you need pointers, I'm no expert but I could help. Better luck next time.
I'm sorry if it was unpleasing in any way, but i just went with the feeling i had at the time and it felt right to me.
Thank you for the comments,
